Visceral obesity is associated with a higher risk of disease recurrence, while sarcopenia is significantly correlated with recurrence and overall mortality among Chinese women with breast cancer. Body composition assessment could serve as a simple and effective approach in breast cancer management.
ObjectiveThis study aims to explore the association of body composition with clinical outcomes in Chinese women diagnosed with breast cancer. MethodA total of 2,948 Chinese female patients with breast cancer have been included in this retrospective study. Body composition mainly includes the measurements of adiposity and muscle mass. Visceral fat area (VFA) is used to measure visceral obesity, while appendicular skeletal muscle mass index (ASMI) is utilized to evaluate sarcopenia. The endpoints of this study are disease-free survival (DFS) and overall survival (OS). The association of the body composition parameters with DFS and OS was statistically analyzed. ResultThe median follow-up time for survivors was 42 months (range, 3 to 70 months). In total, 194 patients (6.9%) had breast cancer recurrence, and 32 patients passed away (1.1%). Among the 2,948 patients included, 1,226 (41.6%) patients were viscerally obese, and 511 (17.3%) patients were sarcopenic. We found that visceral obesity had a significant prognostic impact on DFS (HR, 1.46; 95% CI, 1.10-1.95; p = 0.010) but not on OS (P = 0.173). Multivariate analysis revealed sarcopenia as an independent prognostic factor for DFS (HR, 1.44; 95% CI, 1.02-2.03; p = 0.038) and OS (HR, 2.13; 95% CI, 1.00-4.51; p = 0.049). Body mass index was not significantly associated with both DFS (P = 0.224) and OS (P = 0.544). ConclusionVisceral obesity is associated with a higher risk of disease recurrence, and sarcopenia is significantly associated with increased recurrence and overall mortality among Chinese women with breast cancer. Body composition assessment could be a simple and useful approach in breast cancer management. Further studies can focus on decreasing visceral fat and increasing skeletal muscle mass to improve prognosis in breast cancer survivors.
